Gerdy's tubercle has what attached to it?

• A. Lateral knee fascia
• B. Iliotibial tract
• C. Patellar ligament
• D. Popliteus tendon

Answer: (B)

Gerdy’s tubercle on the lateral proximal tibia is the insertion point for the iliotibial tract. This thick band of fascia lata, formed by the tensor fasciae latae and gluteus maximus, runs down the outer thigh and attaches here to help stabilize the knee by pulling on the lateral side of the tibia, especially when the leg is extended. The other options don’t attach there: the patellar ligament attaches to the tibial tuberosity in front, the popliteus tendon attaches to the posterior tibia, and the lateral knee fascia is a broader term not specifying this insertion.
